COFFEE-POT.

T 0 aZZ whom it may concern:

Be it known that I, HENRY E. Brooms, a citizen of the United States, andresiding at lVallingford, in the county of New Haven and State ofConnecticut, have invented cer tain new and useful Improvements inCoffee-Pots, of which the following is a specification, such as willenable those skilled in the art to which it appertains to make and usethe same.

This invention relates to coffee pots and particularly to devices ofthis class known as percolators; and the object of the invention is toprovide an improved device of this class which is simple in constructionand operation, and which may be easily and thoroughly cleaned wheneverdesired, and in which a minimum amount of heat will serve to operate thedevice; and with these and other objects in view the invention consistsin a device of the class specified constructed as hereinafter describedand claimed.

The invention is fully disclosed in the following specification, ofwhich the accompanying drawing forms a part, in which the separatepart-s of my improvement are desig nated by suitable referencecharacters in each of the views, and in which-- Figure l is a centralvertical section of a cofiee pot made according to my invention; Fig. 2a bottom plan view of a detail of the construction shown in Fig. 1; and,Fig. 3 a partial section on the line 3-3 of Fig. 1.

In the practice of my invention, I provide a receptacle (Z composed ofsheet metal or any suitable material and provided at one side with adischarge spout (a and at the opposite side with a handle and the bottomof which is provided with a circular depression (6* forming acorresponding circular depression or chamber (5" in the bottom of thereceptacle. The receptacle is also provided with a neck a. forming alarge central opening and I also provide a receiver 7) adapted to beinserted into the neck (4 and to fit the opening (67, and which isprovided at or near the top thereof, in the form of construction shown,vith an annular bead 6 which rests on the neck a, and the correspondinginwardly directed annular bead b above which is a flange or rim 6*, andthe receiver Z) is closed by a cap 0 of glass or any other suitablematerial, the base of which is adapted to fit within the flange or rim Nand rests on the inwardly Specification of Letters Patent.

Application filed July 31, 1908.

Patented June 14, 1910. Serial No. 446,257.

directed annular bead b and the cap 0 is provided at the top thereofwith a knob or handle 0 The bottom 6 of the receiver 5 is composed offine wire mesh, finely perforated sheet metal, or any other suitableopenwork material, and placed within the receiver Z) centrally thereofand secured to the bottom I) is a tube (Z, the top portion of which isprovided with laterally directed ports or passages (Z and the top of thetube (Z is also preferably provided with a deflector (Z". I also providea disk 6 which is adapted to approximately fit within the depression orchamber a in the bottom of the receptacle a, and said disk is providedcentrally with a tube 6 which is of such length as to pass up into thetube (Z in the receiver Z) when said receiver is placed in position asshown in Fig. 1, and the tube 6 is also preferably shorter than thecombined height of the receptacle (Z and the neck a thereof, so thatwhen the disk 6 with the tube c is placed in the receptacle a, thereceiver b may be inserted into the neck (a of the receptacle (4, andsaid neck will guide said receiver and the tube 6 will enter the tube(Z. The disk 6 is preferably made of sheet metal and the bottom thereofis provided with radial grooves 6 the dimensions of which increase fromthe perimeter of the disk inwardly and the inner ends of said groovescommunicate with the tube 6 as clearly shown in Figs. 1 and 2.

In practice, the tube 6 with the disk 6 at the bottom thereof is placedin the receptacle (i and said receptacle is filled, or partially filled,with water as shown at f, and the coifee is placed in the receiver 7) asshown at g, and said receiver is inserted into the neck a of thereceptacle, and. in this operation the tube 6 passes into the tube (Z inthe receiver 7). The receptacle (4 is then placed over a suitable heaterof any kind or class, and as the water therein is heated, it passesbeneath the perimeter of the disk 6 as indicated by the arrow (/2,through the radial grooves or passages c in the bottom of said disk intothe tube c and up through said tube into the tube (Z in the receiver 7),and is forced out through the ports or passages (Z in the top of thetube (Z and falls on the coffee in the receiver Z) as indicated by thearrows :0 and this water percolates through the coffee 9' and falls intothe bottom of the receptacle (4 as indicated by the arrows x and thisoperation or flow of the water continues as long as heat is applied tothe bottom of the receptacle a. I also preferably provide the top of thereceptacle a with a vent opening or openings h and another vent opening72, is formed in the bottom of the cap 0, the object of these ventopenings being to prevent a too great increase of pressure in thereceptacle a and in the receiver 6.

It will be understood, of course, that the cap 0 is removable, and saidcap may be detachably connected with the receiver .7) in any desiredmanner.

Hy improved cofiee pot, or the receptacle a, may be placed on or overany suitable heater and it is understood that the heat is applieddirectly to the bottom a of the depression or chamber a in the bottom ofthe receptacle CL and in which the disk 6 is placed, and all that isnecessary to start the circulation of water, or the feeding of waterthrough the tube 6 is to heat the water into the radial passages e inthe bottom of said disk and at the lower end of the tube 6 and this isquickly done. The inner ends of the radial passages e are enlarged so asto form a considerable chamber or recess around the lower end of thetube 6 as clearly inclicated at e in Figs. 1 and 2, and this facilitates the circulation of the water as hereinbefore described. It will beunderstood, of course, that the operation of my improved coffeepercolator is, in the main, the same as other devices of this class, butby means of my improvement, I provide for a more rapid circulation ofWater through the tube 6 and a consequent freer discharge of water ontothe coffee in the receiver Z), and the brewing of the coffee is effectedmore quickly and in a more thorough manner than is possible with otherdevices of this class as usually constructed.

Having fully described my invention, what I claim as new and desire tosecure by Letters Patent, is

1. In a coffee pot, a receptacle provided at the top with a neck, acofiee receiver adapted to be inserted into said neck and provided witha removable cap and an openwork bottom and centrally of said bottom witha tube which is secured thereto and which extends upwardly and the topof which is provided with discharge ports or passages, and a feed tubeprovided at one end with a disk adapted to rest on the bottom of thereceptacle, and the other end of which is adapted to enter the tube inthe receiver, the bottom of said disk being flat and provided withradially arranged passages which communicate with said tube, thedimension of said passages in creasing from the perimeter of said diskinwardly to said tube.

2. A coffee pot, comprising a receptacle, the bottom of which isprovided with a circular depression forming therein a correspondingcircular depression or chamber, said receptacle being also provided atthe top thereof with a neck, and a receiver adapted to be inserted intosaid neck and provided with an openwork bottom centrally of which issecured an upwardly directed tube having discharge ports or passages atthe top thereof, and a tube provided with a disk adapted to rest in thedepression or chamber in the bottom of the receptacle, the bottom ofsaid disk being fiat and provided with radial passages which communicatewith said tube and the dimensions of which increase from the perimeterof said disk inwardly to said tube, and the upper end of said tube beingadapted to enter the tube in the receiver when said receiver is insertedinto the neck of the receptacle, said receiver being also provided witha removable cap, and the cap and receptacle being provided with vents.

In testimony that I claim the foregoing as my invention I have signed myname in presence of the subscribing witnesses this 28th day of July1908.
